BUBBLETONE BLOCKCHAIN GLOBAL TELECOM ECOSYSTEM WITHOUT INTERMEDIARIES: SMART CONTRACTS ALLOW DIRECT INTERACTION BETWEEN MOBILE OPERATORS, SUBSCRIBERS AND SERVICE PROVIDERS 2 Welcome message from Yury Morozov, Founder Meet our new blockchain-based platform project. Our company has been in telecom business for more than 20 years. Seventeen years ago we were among the first to create a platform for intelligent communication services, including fixed-mobile convergence at Allo Incognito company operating in Russia. Yury Morozov Founder For more than 18 years we have been successfully developing our own MVNO operator company with a client base of over 250,000 subscribers. But as an MVNO operator offering its services only in limited areas, we are still unable to provide our clients with global roaming service despite many efforts. Such a project would require us to sign contracts with about many hundreds global operators, pay a lot of money for technological convergence, check the quality of the services provided (voice, data, SMS, MMS, real-time billing, signaling, etc.) and also guarantee 300,000500,000 commitments per year. Obviously, a project of such scale demands vast material and human resources. To provide roaming services to our subscribers, we developed and brought into commercial operation a special OTA platform which makes it possible to remotely swap between mobile profiles of a SIM card, practically on the fly. It looks like you simply bought a new local SIM card and inserted it into your mobile phone. We partnered with operators that currently provide services to their subscribers in more than 80 countries and who agreed to sell their mobile profiles on condition of paying deposits to these operators. In fact, we can already provide services to our clients at local rates without roaming in more than 80 countries. But there is a big inconvenience: buying profiles involves paying a deposit in each country, setting up online billing and, for many countries, completing a KYC form. What we have today: Operational platform that is able to upload mobile profiles on subscribers' SIM cards; Operational applet certified by one of the world's largest SIM card manufacturers, Oberthur Technologies (OT) and Safran Identity & Security (Morpho), which determines whether the subscriber is in his home or guest network. Depending on the settings, it automatically swaps the home mobile profile for the one newly downloaded by our platform. Beta version of the messenger with a playful name - Bubbletone - but serious technological capabilities. The Beta version is already available in the Google Play Market and the Apple App Store. We chose a meaningful name: while the messenger is a full-featured working tool for users, it's as easy to use as blowing bubbles. We believe that this fun brand name will make our messenger more recognizable around the world. 3 The Bubbletone app contains more than 100 functions, each being in high demand by users. For our current project, the most important functions are: Retaining your mobile number in the app during remote swapping of the SIM card profile. Subscribers will be able to receive incoming calls via an IP channel and also pay for local mobile service bundles in the visited country. Using Bubbletone as the first client of a decentralized network based on blockchain technology (explained below), which we are developing. Blockchain made it possible for us to radically change the rules of the game: we simply eliminated roaming. Collaboration by mobile operators from different countries to make roaming possible involves huge expenditures on infrastructure support. In fact, the provision of services to a network subscriber in another network requires complex interactions between various equipment of the providers. Our solution will let operators cast aside most of this infrastructure because many requirements, such as validity, integrity and indisputability, are covered by the technology itself. We're not daydreamers we know exactly which minimum data are processed by opera- tors during service provision and what the process looks like. In our system, the interaction between operators is encoded in a reliable and simple smart contract that contains every- thing necessary to provide roaming services. Why should someone visiting another country pay 810 times more than a local? This is unreasonable. Plus, the poorer the country, the more expensive the roaming. In our system we change the "push" paradigm, where operators "force" their subscribers into another operator's network, for "pull", where operators see the new clients themselves, securely identify them, and connect them to their own networks. Our smart contract is a separate incontestable agreement between two operators and the clients themselves that is enforced automatically. In short, our code chooses a suitable operator for a client that will provide that client with roaming or any other communication service and creates a smart contract via a single transaction in which each party will "sign" for each action, attaching the necessary data to the contract every time (data will be securely encrypted so as to be accessible only by the parties.) Each "signature" is written into the blockchain and can be used as a reliable source of information on the status of the contract. What are its benefits? Transactions are incontestable. Operations conducted in blockchain are nearly impossible to fake or hide. This factor is important both for operators and their clients. Data are safe. An entire blockchain is kept on many nodes within the network, in many copies, so the chance of data loss is extremely low. The transaction error rate is minimized, as each action is controlled by a strict code on the operators' nodes. 4 Less traffic is transmitted among operators all interactions are now conducted via a decentralized p2p network. Any additional code the system runs on is void of sensitive information that could be stolen. The only data requiring protection are the private keys of the participants. Other benefits of a specific blockchain are given below. We have analyzed many blockchain platforms and found them not entirely suitable for the telecommunications industry, as their transaction processing speed is rather low and we don't want to let our clients down. Our platform of choice is Graphene, which underlies the decentralized exchange BitShares and such widely known projects as Steemit, Golos and EOS. Our developers promise us over 10,000 transactions per second, though, to tell the truth, 5,000 would be enough at the start. Also, the first prototype of the first node has already been published on GitHub https://github.com/Clementvale-LTD. . With our solution, operators will be able to publish their price quotes in the blockchain network and automatically get connected clients. The clients will receive all the data necessary for connection with just a couple of transactions and the operator will securely reserve the money to pay for the services. The amount of unnecessary traffic and hardware that will be freed up due to this solution is quite striking. This isn't magic or a trick, but a new class of algorithms with inherent ready-to-use functions for companies providing information services. Consider the following benefits: 1. When a SIM card is first sold, the home operator validates the client and sends encrypted digital proof of the client's validity into a blockchain. As a result, when the client goes to another country, there's no need to provide their ID to get another SIM card. 2. Roaming operators will only need to promptly offer their services and price quotes, and the network will distribute this information and use it to bill clients itself. 3. The offers will be regulated by the law of supply and demand, so technical and market share dominance will become less important than, for instance, the quality of service. Isn't this the cellular communication we always wanted? 4. We are making communication services exponentially more affordable and are fighting inequality. The cost to use and support our system is significantly less than what you'll find with other operators today. 5. Our system has many technological advantages (and some shortcomings, of course). For more information, see the project's white paper or simply ask us any questions you may have. 5 We developed a special economy for the telecom industry. We have two tokens: One of them is stable and equals 1 SDR used in telecommunications. We named it SDR (SDR Token). It's the unit of payment given to providers for their services, i.e., the price of services is measured in these units. Everyone needs SDR tokens, and their amount is unlimited, just like amount of services is unlimited. The second token is UMT. It's necessary for creating smart contracts, and all service providers require it. For more information on tokenomics, see our white paper. While our blockchain platform is still under development, we have already received several requests from existing business projects to transfer their business processes to our blockchain. They need stable tokens and a quick blockchain platform, and, like ourselves, they got tired of the many intermediaries that sometimes earn more than those who actually provide services and conduct business. So, our project to kill roaming is only the beginning.

Executive Summary "Blockchain in Telecom" ecosystem provides direct interaction between end-users, mobile operators and service-providers via smart contracts. This reasonable eliminates hundreds of intermediators, dramatically reduces costs of mobile services (up to 10 times while going abroad), and saves years and millions of $$ on implementation of the old- fashioned and ineffective roaming technology. How it works: any mobile carrier could publish its own prepaid tariff plans ("Offers") as smart contracts. These Offers are visible to all other operators and their subscribers. By selecting an Offer, a new "Request" smart contract is created, with the Digital Identity of a subscriber and Payment transaction. As a result, the Offer issuer identifies the user and receives money, and starts servicing the subscriber directly, with local price and high quality. The same business process is available for any non-telecom service provider (like music, TV or cloud services) who is interested in distributing its own Offers among multimillion customer bases of mobile operators. The Blockchain ecosystem consists of a limited number of high performance servers ("Nodes"), which belong to the crypto community. It means that any crypto holder could buy a license to manage the Node, and start earning by processing the smart contracts. 10 The more operators and service providers are connected to the "Blockchain in Telecom" ecosystem, the more "smart contracts" are to be processed, the more is the revenue and value of each Node. Our approximated projection is 10x annual growth of Smart Contracts in the ecosystem based on reasonable expectations of telecom services growth and observable market data. We believe, what this is combined with Low Risks, because we're a proven team with 20 years' experience in telecom industry. During this period, multiple telecom and software development businesses have been created: a. Mobile Virtual Network Operator under brand "Allo Incognito" (250K Premium Subscribers) b. "Bubbletone" messenger with 100+ useful features. It's customized for the needs of mobile operators to provide additional revenue streams on voice calls and SMS from the app and other telecom services. Beta version is already available at App Store and Google Play. c. Global Mobile Data Exchange developed for mobile operators who are interested in global coverage services for their subscribers. Currently local prices on mobile services are already available in 80+ countries. We are running an ICO to gather funds mainly to provide our users with innovative and cross-border services and for further development of the blockchain platform, marketing, expanding and sustainability of the ecosystem. . 11 2. Glossary Regional telecom carrier (hereinafter "Carrier") - a company with the corresponding license, which is providing telecom services to its subscribers, and possess a non-dominant share of a local market. SDR (Special Drawing Rights) - a unit of accounting of the International Monetary Fund ("IMF") for International Settlements, which is actively used by the mobile carriers for settlement. The cost of SDR is calculated as a basket of market rates of five world currencies: 41.7% of the US dollar, 30.9% of the Euro, 10.9% of the Chinese yuan, 8.3% of the Japanese yen and 8.1% of the pound sterling. SDR token a token pegged to SDR (Special Drawing Rights). This token is used as a means of payment for services of mobile carriers and service-providers. UMT token (Universal Mobile Token) - a token with a limited amount specified on the ICO. A small number of UMT should be put into each Smart Contract when it is created to perform transactions under the Smart Contract. UMT tokens can be used as a means of payment for telecommunications services on the Bubbletone platform. Specifically, UMT tokens can be used on a user's balance in the Bubbletone messenger app as payment for sending messages and making voice calls in public switched telephone networks. To replenish the balance in the Bubbletone app, a user can buy UMT tokens making payment with fiat currencies, crypto currencies or SDR tokens through the payment gateway inside the Bubbletone platform. Crypto currencies, fiat currencies or SDR tokens will be exchanged into UMT tokens and will be deposited as UMT tokens on the balance of the Bubbletone app user. Proof of Importance (POI) - a further development of Proof - of - Stake consensus in the field of Telecom. It is a consensus based on the net transfers: how much has been 'spent' in the past 30 days. SLA (Service Level Agreement) - Agreement on the level of service which represents a formal agreement between the customer and its supplier, containing a description of services, rights and obligations of the parties and, most importantly, a consistent level of quality of the service. 12 3. Global market for messaging, mobile traffic and roaming 3.1. The volume of global mobile traffic The global mobile traffic may reach 19 exabytes (billions of gigabytes) per month in 2018 (Cisco Visual Networking Index Global Mobile Data Traffic Forecast for 2013 to 2018).The process of digitizing our lives is irreversible. According to research from 2015 and 2016, more than 80% of the population in developed countries have access to the Internet, and more than 60% of Europeans own smartphones, with almost constant access to the network. The expected growth in mobile traffic will be, among other things, the result of the continued increase in mobile Internet connections of personal devices and machine-to-machine connections (M2M), whose number will exceed 10 billion in 2018 (Cisco: in the period from 2012 to 2017 the volume of mobile traffic will grow 13 times). The development of these trends is facilitated by the popularity of instant messengers (IM). Internet traffic of messengers surpassed voice communications and the volume of SMS traffic in 2016 for the first time. By the number of text messages, IMs will surpass SMS by 10+ times by 2020. 3.2. Tourists consume less or no traffic because of expensive roaming There are more than 1.2 billion travels per year globally, growing by 4% annually. According to Starhome Silent Roaming research, 70% of subscribers disable data roaming, and just 1% of subscribers consume 80% of all traffic in roaming Our experts consider this to be a consequence of high prices. This means that there is substantial hidden demand for cheaper traffic from tourists. 13 3.3. There are more than 900 potential partners for Bubbletone Blockchain Creation of the Bubbletone Ecosystem is happening with assistance and in partnership with mobile carriers and service-providers around the world 3.4 Potential of Bubbletone Blockchain with further development of eSIM technology Mobile device manufacturers have been increasingly producing equipment that only works with embedded SIM. Latest examples are Apple Watch Series 3, Gear S2 Classic 3G and others. Growing is the number of smartphones that have embedded SIM as the main connectivity component or are equipped with it along with the traditional SIM-cards. Smart Insights (https://www.smartinsights.net/reports) forecasts the sales of eSIM- enabled handsets would total 346 million to 864 million units by 2020. In the near future 100% of devices will be eSIM-enabled. In the IoT segment the pace of eSIM adoption is even higher. For embedded SIM users, the Bubbletone blockchain offers an ecosystem where new economic relationships can be made by connecting mobile devices to a specific network. Each user will have the opportunity to choose a network operator and to switch to another operator including the MNP procedure without the involvement of operators and retailers. This approach reduces the costs of subscriber acquisition, starter kits production and logistics. As a result of this change, the operators can use new mechanisms to reduce the price of services for local rates, as compared to selling physical SIM-cards in retail stores. In the coming 3 to 5 years, the Bubbletone blockchain will be able to process over 30% of all connections to mobile networks worldwide. To implement this process, vendors of mobile devices will just have to connect to Bubbletone blockchain. We are creating a non-geographic mobile profile (GMP), which is not dependent on the legal requirements of any specific country where mobile service is rendered. This will allow for the creation of a universal product operational throughout the world according to uniform rules. GMP allows registration of mobile devices and loading of the mobile profile of the local operator via SMS or https channel in accordance with eSIM standards (SGP-21), Security Mechanism for the SIM (3GPP TS 23.048), and other solutions ensuring secure loading of profiles to mobile devices. This gives the user the option to select the necessary network operator and use mobile services at local rates worldwide. 14 For the GMP to operate correctly, we plan to maintain the relevant telecommunications infrastructure and also to sign agreements with network operators throughout the world to ensure the GMP is registered in their networks. To accomplish this, we are going to use the infrastructure of our MVNO network. Agreements with operators will be signed according to the standard roaming procedure utilizing the existing infrastructure of transit operators (SS7,IPX/GRX). GMP will change the current process of connecting a mobile device to the mobile operator eliminating the involvement of retail chains and SIM card logistics. 4. Value for carriers, for subscribers and for crypto community Bubbletone Blockchain will create a fair and transparent ecosystem for the telecom industry to substitute for current ineffective and costly roaming technology. Bubbletone Blockchain should allow: Carriers to cut costs and increase revenues, Subscribers to gain access to local prices worldwide instead of high roaming charges and to earn bonuses for activities that can be spent on communication services and other services from the participants of Bubbletone Blockchain, Crypto-Community - to enjoy rapid growth of income. Bubbletone Blockchain, as well as other global Blockchain platforms, will belong to Crypto Community 4.1. What is roaming and roaming agreements In the context of mobile phone networks, the word "roaming" is used when a mobile phone is used outside of the range of its home network and connects to another available cell network. For example: should subscribers travel beyond their mobile carrier networks, their cell phone would automatically hop onto another phone company's service, if available. The legal roaming business aspects negotiated between the roaming partners (mobile carriers) for billing of the obtained services are usually stipulated in so-called roaming agreements. The GSM Association broadly outlines the content of such roaming agreements in standardized form for its members. In order for a subscriber to be registered on a visited network, a roaming agreement needs to be in place between the visited network and the home network. This agreement is established after a series of long testing processes, various legal and financial commitments, and other cumbersome procedures. The goal of the Bubbletone Blockchain platform is to eliminate all of the above long, complex and costly procedures, creating a new market for thousands of telecom carriers and opening affordable mobile services for silent roamers. Moreover, the platform creates a synergy between the telecom business and service providers outside of the telecom market. 4.2. Problems for the regional carriers 15 The technology of roaming is cumbersome, expensive and hard to implement. It bears cost on the integration of carriers, measured in years and millions of dollars. As a result, the roaming services market has become virtually monopolized by the major carriers, and it is closed to regional carriers. The latter actually lose their subscribers at a time when they are traveling abroad. (GSMA International Roaming explained) From the time of market entry of instant messengers all carriers began to lose a substantial part of their revenues on voice traffic and SMS. A project to launch its own messenger for any carrier involves considerable time and capital cost. In addition, messengers from carriers usually lose to popular messengers by their functions and prevalence. For the regional carriers, it is difficult to compete with large players who invest significant funds in design and marketing of new services. One more problem is a decreasing average revenue per user because of strong competition between operators. Small and medium mobile operators have limited budgets on R&D and marketing to implement new services in short period. As a result, they are not able to compete with large mobile carriers on equal terms. 4.3. Solutions of Bubbletone Blockchain for carriers By connecting to Bubbletone Blockchain, carriers will avoid the need to enter into roaming agreements. Mobile carriers will be able to connect to Bubbletone Blockchain through a simple API (Application Programming Interface). They do not have to go through a complicated and lengthy process, as in the case of roaming. 16 They will also be able to provide for their subscribers a Bubbletone messenger, with integrated tariffs plans and customized wallpaper with their logo and colors. They will be able to provide to their subscribers the opportunity to keep their mobile number while traveling abroad and, additionally, save on roaming. Which means that the home mobile carrier will not lose revenue from incoming and outgoing calls, which otherwise would have gone to another operator. In addition, mobile carriers will be able to provide services to subscribers coming to their country with acquisition cost close to zero. According to our calculations, to attract a subscriber today, regional mobile carriers spend about 20%-30% of their LTV (Lifetime Value). Connection of new carriers to the Blockchain is carried out by the consensus of existing players, which makes the process transparent, excludes patronage, and also significantly reduces the appearance of scammers. 4.4. Problems of subscribers Being inside their home network, the subscriber does not have the ability to quickly switch between carriers in case of poor-quality communication because domestic carriers do not have an effective national roaming mechanism. Traveling subscribers have to significantly overpay for services of foreign carriers because the roaming market is monopolized by Mobile Network Operators. Traveling subscribers have three alternatives for roaming, but each of them has its own disadvantages: Local SIM card: the need to look for the point of sale to set up a local SIM card, which may be complicated by a possible language barrier and sometimes requires several hours; risk of losing the user's main SIM card; change of the user's home number. Global SIM card: higher rates than local SIM cards; separate balance; change of the user's home number; risk of losing the user's main SIM card. Wi-Fi hotspots: the need to search for an access point; permanent reconnection between hotspots; these points usually require a password, which disrupts the continuity of the network connection. 4.5. Solutions of Bubbletone Blockchain for subscribers To avoid roaming charges and stay connected with their home number outside of their home network, any subscriber can set up the Bubbletone Messenger and buy a local tariff in the country they visit. The beta version of the Bubbletone messenger is now available for download in the App Store and Google Play. The beta version of the Bubbletone Messenger already has enhanced security and unique features: 1. Audio and video calls. 2. Group chats and SMS chats 3. Burning messages after reading. 4. Sending messages to the future. 5. Sending SMS from the messenger onto GSM network. 6. Stickers and animations. 7. Sharing photos, videos and large files. 8. Record voice messages with pre-listening. 9. Request geolocation of subscriber and contacts. 17 10. One account for multiple devices with message synchronization and built-in cloud storage. It is already supported by the mobile carrier "Allo Incognito" and negotiations are being held with several other carriers. In the future, we are planning to develop new functionality for the Bubbletone messenger as a part of Bubbletone Blockchain: 1. A technical capacity to buy a virtual number in 60 countries around the world and order communication packages in 100+ countries around the world, according to their local tariff plans 2. The ability to enable automatic selection of the carrier by the criteria of price or quality of communication services 3. Access to independent rating of mobile services provided by the carriers. Each user can estimate the quality with one "click" in the Bubbletone messenger, and his/her choice will be recorded inside the Blockchain 4. Make P2P payments in crypto and fiat currency around the globe 5. With a built-in voting platform based on blockchain, users can organize voting contests, business meetings, and give honest ratings to products and services 6. Videoconferences with a large number of participants 7. Hidden chats and contacts in case an unidentified person appears in front of the device. 4.6. The crypto- miners problem Apart from volatile exchange rates, crypto- miners have two other problems. 1) The constant "arms race" because of the increasing complexity of mining. 2) The problem of the utility-value of the earned crypto currency. Most crypto assets do not yet provide an opportunity to buy real goods and services with them. Also, they are purely speculative. 4.7. Solutions of Bubbletone Blockchain for miners Bubbletone Blockchain gives miners an opportunity to process smart-contracts created by mobile carriers and service providers, and earn reward on this business. 18 Miners in Bubbletone Blockchain will be able to engage in useful work. Instead of searching for artificial hashes, the crypto-miners will be processing transactions for the provision of communication services and other online services. Miners can earn Universal Mobile Tokens (UMT), which are required in Bubbletone Blockchain to be used as a means of payment to pay fees for processing the transaction. UMT is a universal token to make a smart contract executable in Bubbletone Blockchain. When we connect new carriers and subscribers to the system, the number of transactions will grow. For mining in the system, Proof of Importance (POI) consensus will be used. It's a further development of "Proof - of Stake" consensus in the field of Telecom. In order to start processing the transactions, crypto- miner should buy UMT and put them onto deposit. There are two contribution levels in Bubbletone Blockchain: Level 1 - a Super Node a high-performance server which has to be switched online and tuned according to SLA (Service Level Agreement) to execute the Smart Contracts. It will require a deposit of 1 million UMT. In addition to commission fee on transactions, a Super Node holder will be able to receive a share from the daily payment from the Network Development Fund (NDF). The purpose of NDF is to support the nodes until there will be enough transactions for them to process with profit. So, we plan to develop the network in two years. Level 2 a Mini Node any computing device (even smartphone) to assist the Super Nodes in transaction processing. It will require a deposit of 1,000 UMT. Each Mini Node must be attached to a Super Node of his choice. Super Nodes will be able to give tasks to Mini Nodes such as validating of smart contracts. The commission fee on transaction processing will be distributed as follows: 45% goes to Super Nodes. Out of these Super Nodes may provide additional bonuses to the Mini Nodes attached to them. 30% of income is split among Mini Nodes attached to a Super Node. This Bonus can be earned by assistance the Super Node in transaction processing. 25% goes to the Community Development Fund to ensure constant development of the system and to exclude the Deadlock situation, where there may be not enough UMT to perform the transactions. 19 4.8. Proof-of-Importance (POI) consensus Proof-of-Importance is a Blockchain consensus mechanism introduced by NEM. Bubbletone Blockchain uses its version modified for the telecom services. It functions similarly to Proof-of-Stake: nodes need to 'vest' an amount of currency to be eligible for creating blocks and are selected for processing a transaction roughly in proportion to some score. In Proof-of-Stake, this 'score' is one's total vested amount, but in Proof-of-Importance, this score includes more variables. The calculations follow from the math of network clustering and page ranking. For a user who owns a Mini Node, the primary inputs of his POI rating are: 1) Amount of currency in deposits for purposes of creating a node (minimum 1000 UMT) 2) Activity in traffic consumption this type of measurement is better than measuring outbound traffic as it guards against bots and spammers who could increase their rating by artificial means. 3) Activity in transaction generation e.g. ordering services in the past 30 days, with more recent transactions weighted more heavily. The importance rating addresses primary criticism of proof-of-stake that people simply hoard as many coins as possible and reap the rewards from that. This concentrates wealth while discouraging transactions. The importance rating means that spreading tokens around will increase it. For a user who owns a Super Node, the primary inputs of his POI rating are: 1) Number of days from the past 100 days, when Super Node was online and performed at the level required by SLA. 2) Super Node standing in the list of best performing Super Nodes in the network. 5. How it works? Initially, any mobile carrier could publish its own prepaid tariff plans ("Offers") as smart contracts. These Offers are visible to all other operators and their subscribers. By selecting an Offer, a new "Request" smart contract is created, with the Digital Identity of a subscriber and payment transaction in SDR tokens. Each transaction has UMT to be processed by Super Nodes. As a result, the Offer issuer identifies the user and receives money, and starts servicing the subscriber directly, with local price and high quality. The same business process is available for any non-telecom service provider (like music, TV or cloud services) who is interested in distributing its own Offers among multimillion customer bases of mobile operators. The process of creating and executing of smart contracts is seamless for customers and takes about a minute. Direct connection to a local operator provides low rates and high LTE quality, with easy management using Bubbletone mobile app. We're planning to issue Global Mobile Profile in 2019 to make mobile devices connected. This profile will be embedded into devices by vendors, so any end-user will be able to select required mobile provider at home and abroad in one click. 20 Crypto-miners can earn Universal Mobile Tokens (UMT), which ar

The first decentralized telecom ecosystem that allows mobile network operators, phone users and service providers to interact directly.
